Installing a deadbolt costs between $100 and $275 including both the lock and labor. The exact price depends on the quality of the deadbolt you choose, the complexity of the installation, and the locksmith rates in your area. Understanding these factors helps you budget properly and choose the right security level for your home.
This guide covers everything you need to know about deadbolt installation costs in 2026. We will explain ANSI security grades, compare smart and traditional locks, break down labor costs, and help you decide whether to hire a professional or attempt the installation yourself.
Breaking Down the Total Cost
A complete deadbolt installation involves two main expenses: the lock itself and the labor to install it. Here is how these costs typically break down.
Deadbolt Hardware Costs
Basic deadbolts start around $25 to $50 for standard models from hardware stores. Mid-range deadbolts with better security features cost $50 to $150. High-security deadbolts with advanced pick resistance and drill protection run $150 to $300 or more.
Labor Installation Costs
Professional locksmiths charge $50 to $100 per hour for installation services. A straightforward deadbolt replacement takes 30 to 45 minutes. Installing a deadbolt on a door that has never had one requires drilling new holes and takes 45 to 60 minutes. Complex installations with smart locks or security upgrades may take 60 to 90 minutes.
Combined Total Range
When you add hardware and labor together, expect to pay:
- Basic installation: $100 to $175
- Mid-range installation: $150 to $250
- High-security installation: $200 to $400+
These prices assume standard door preparation. Additional charges apply for non-standard doors, repairs to damaged frames, or custom security modifications.
Understanding ANSI Security Grades
The American National Standards Institute (ANSI) rates deadbolts on security and durability. These grades help you compare locks objectively. Every reputable deadbolt displays its ANSI grade on the packaging.
Grade 1 Deadbolts
Grade 1 is the highest security rating for residential deadbolts. These locks withstand 1 million open and close cycles, 10 strikes of 75 pounds of force, and significant drill resistance. Grade 1 deadbolts cost $100 to $300 and provide maximum security for front doors and vulnerable entry points.
Best for: Front doors, homes in high-crime areas, and anyone prioritizing security over cost.
Grade 2 Deadbolts
Grade 2 offers excellent security for most residential applications. These locks withstand 800,000 cycles and 5 strikes of 75 pounds of force. Grade 2 deadbolts cost $50 to $150 and represent the sweet spot between security and affordability for typical homeowners.
Best for: Side doors, back doors, interior garage access doors, and budget-conscious buyers who still want solid security.
Grade 3 Deadbolts
Grade 3 is the minimum acceptable rating for residential use. These locks withstand 200,000 cycles and 2 strikes of 75 pounds of force. Grade 3 deadbolts cost $25 to $75 and provide basic security suitable for low-risk situations.
Best for: Interior doors, sheds, and secondary structures where maximum security is not critical.
How to Check the Grade
Look for the ANSI grade printed on the deadbolt packaging or the lock face. If no grade is listed, the lock likely failed testing or was not submitted for certification. Stick with Grade 2 or Grade 1 for all exterior doors.
Smart Deadbolt Costs and Considerations
Smart deadbolts have become increasingly popular, offering keyless entry, remote access, and integration with home automation systems. These features come at a premium price.
Basic Smart Deadbolts
Entry-level smart deadbolts with keypad entry cost $150 to $250. These allow you to create multiple entry codes and eliminate the need for physical keys. Installation is similar to traditional deadbolts, keeping labor costs consistent at $50 to $100.
Connected Smart Deadbolts
Mid-range smart deadbolts with WiFi or Bluetooth connectivity cost $200 to $350. These connect to smartphone apps, allowing remote locking and unlocking, activity monitoring, and temporary access codes for guests. Installation requires basic electrical knowledge but does not significantly increase labor time.
Premium Smart Deadbolts
High-end smart deadbolts with advanced features like fingerprint recognition, video integration, and voice assistant compatibility cost $300 to $500. Installation may take longer due to app setup and system integration, potentially adding $25 to $50 to labor costs.
Ongoing Costs to Consider
Smart deadbolts require battery replacement every 6 to 12 months, costing $10 to $20 annually. Some advanced features require subscription services for video storage or premium app functions, adding $3 to $10 per month.
Labor Cost Details
Understanding how locksmiths charge for installation helps you evaluate quotes and budget appropriately.
Hourly vs Flat Rate Pricing
Most locksmiths charge flat rates for standard deadbolt installation rather than hourly billing. This protects you from unexpected costs if complications arise. Typical flat rates are $75 to $150 for straightforward replacements.
Hourly billing, when used, ranges from $50 to $100 per hour with a one-hour minimum. This approach is more common for complex jobs or when the scope of work is unclear until the technician arrives.
Factors That Increase Labor Costs
Several situations increase installation time and cost:
New door preparation: Drilling holes in a solid door takes longer than replacing an existing deadbolt. Add $25 to $50 for new installations.
Metal or fiberglass doors: These materials require special drill bits and slower work to prevent damage. Expect $25 to $75 additional charge.
Door alignment issues: If the door does not close properly or the frame is damaged, adjustments are needed before lock installation. Frame repairs cost $50 to $200 depending on severity.
Multiple locks: Installing deadbolts on several doors during one visit often qualifies for volume discounts. Ask about reduced rates for whole-house security upgrades.
Geographic Variations
Labor costs vary significantly by location. Urban areas with high living costs like New York, San Francisco, and Los Angeles charge 30% to 50% above national averages. Rural areas may have higher rates due to travel distances, while suburban markets often offer competitive pricing.
DIY vs Professional Installation
Installing a deadbolt yourself can save $50 to $150 in labor costs. However, DIY installation is not right for everyone. Consider these factors before deciding.
When DIY Makes Sense
You have basic tools: A drill, hole saws, screwdrivers, and a chisel are the minimum requirements. Most homeowners own these tools or can borrow them.
Your door is prepped: Replacing an existing deadbolt is straightforward. The holes are already drilled, and installation takes 15 to 30 minutes.
You are handy: Basic mechanical skills and attention to detail ensure proper installation. Following the included instructions carefully produces professional results.
When to Hire a Professional
Your door needs new holes: Drilling precise holes in the correct locations requires templates and experience. Mistakes can ruin an expensive door.
You have a high-end lock: Expensive smart locks or high-security deadbolts often have complex installation requirements. Professional installation protects your investment and ensures warranty coverage.
Your door or frame is damaged: A locksmith can assess and repair underlying issues that prevent proper lock function. DIY installation on damaged doors leads to ongoing problems.
You need multiple locks: Professional locksmiths work efficiently and ensure consistent installation quality across all doors. The time savings often justify the cost for whole-house projects.
DIY Cost Breakdown
Doing it yourself requires purchasing the lock plus minimal supplies:
- Deadbolt: $25 to $300 depending on grade and features
- Basic tools: $0 if you already own them, $50 to $100 if you need to buy
- Installation supplies: $5 to $15 for screws, lubricant, and finishing materials
Total DIY cost ranges from $30 to $415 depending on lock quality and tool ownership.
Choosing the Right Deadbolt for Your Needs
Selecting the appropriate deadbolt involves balancing security requirements, budget constraints, and convenience preferences.
Assess Your Security Needs
High-risk areas: Choose Grade 1 deadbolts with pick-resistant cylinders and reinforced strike plates. Consider additional security measures like door jamb reinforcement.
Average neighborhoods: Grade 2 deadbolts provide excellent protection without premium pricing. Look for models with anti-drill features and hardened steel bolts.
Low-risk situations: Grade 3 deadbolts offer basic protection adequate for interior doors or detached sheds where theft risk is minimal.
Match Features to Your Lifestyle
Frequent visitors: Smart deadbolts with temporary access codes let you grant entry without copying keys. This is ideal for vacation rentals, dog walkers, or house cleaners.
Technology preferences: If you enjoy smart home devices, connected deadbolts integrate with your existing systems. If you prefer simplicity, traditional keyed deadbolts work reliably without batteries or apps.
Physical considerations: Elderly residents or those with arthritis may prefer keypad entry over fumbling with keys. Families with children benefit from locks that automatically engage when the door closes.
Quality Brands to Consider
Established manufacturers with proven track records include Schlage, Kwikset, Yale, Medeco, and Mul-T-Lock. These companies offer reliable warranties and widely available replacement parts. Avoid generic or unknown brands that may not meet ANSI standards.
What to Expect During Installation
Knowing the installation process helps you prepare and evaluate the work quality.
Pre-Installation Preparation
Clear the area around the door and ensure adequate lighting. Remove decorations or obstacles that might interfere with the technician's work. If you have pets, secure them in another room to prevent accidents and distractions.
The Installation Process
Assessment: The locksmith examines your door, frame, and existing hardware to identify any issues.
Removal: Old locks are removed carefully to avoid damaging the door.
Preparation: New holes are drilled if necessary, and the strike plate location is verified.
Installation: The deadbolt mechanism is inserted, faceplates are secured, and alignment is checked.
Testing: The locksmith tests the lock multiple times from both sides, checks the strike plate engagement, and ensures smooth operation.
Cleanup: Work areas are cleaned, and old hardware is either left with you or disposed of as requested.
Post-Installation Checklist
Before the locksmith leaves, verify:
- The lock operates smoothly with the key
- The deadbolt extends fully into the strike plate
- The door closes and latches properly
- You received all keys and instructions
- Warranty information is documented
Warranty and Maintenance Considerations
Protecting your investment requires understanding warranty coverage and performing basic maintenance.
Typical Warranty Coverage
Quality deadbolts include warranties ranging from lifetime limited coverage to specific year guarantees. Most cover mechanical defects but exclude damage from improper installation, forced entry attempts, or normal wear.
Professional installation often includes a labor warranty covering installation defects. This typically lasts 30 to 90 days and ensures proper function of the installed lock.
Basic Maintenance Tips
Lubricate annually: Apply graphite powder or Teflon-based lubricant to the keyway and moving parts. Avoid oil-based lubricants that attract dirt.
Check screws monthly: Ensure mounting screws remain tight. Loose screws cause misalignment and premature wear.
Clean the keyway: Compressed air removes dust and debris that interferes with smooth operation.
Test regularly: Operate the lock weekly to catch problems early. Stiff operation or difficult key insertion indicates maintenance needs.
Frequently Asked Questions
How long does deadbolt installation take?
A straightforward replacement takes 30 to 45 minutes. New installations requiring door preparation take 45 to 60 minutes. Smart lock installations with app setup may take 60 to 90 minutes.
Can a locksmith install a deadbolt I bought myself?
Yes, most locksmiths will install customer-supplied deadbolts. However, they may charge the same labor rate and will not warranty the hardware itself. Purchasing through the locksmith often includes better warranty coverage.
What is the difference between single and double cylinder deadbolts?
Single cylinder deadbolts operate with a key outside and a thumb turn inside. Double cylinder deadbolts require keys on both sides. Double cylinders provide extra security but can trap you inside during emergencies. Check local building codes before installing double cylinder locks.
Do I need a deadbolt if I have a handle set with a lock?
Yes, handle set locks provide minimal security and are easily defeated. Deadbolts offer significantly better protection because the bolt extends deep into the door frame. Every exterior door should have both a locking handle and a separate deadbolt.
Will a new deadbolt fit my existing holes?
Most deadbolts follow standard sizing with a 2-1/8 inch diameter hole and 1-inch diameter latch hole. However, backset distances (the distance from the door edge to the hole center) vary between 2-3/8 and 2-3/4 inches. Verify measurements or choose adjustable deadbolts that fit both sizes.
Why do locksmith prices vary so much for the same service?
Prices reflect differences in overhead costs, technician experience, and service quality. Established companies with insurance, training programs, and quality guarantees charge more than independent operators. Extremely low prices often indicate uninsured workers or bait-and-switch tactics.
